I have it currently set to PXE Boot via Dnsmasq as "dhcp-boot=pxelinux.0,,192.168.1.200"
PXE Server works great and can get computers imaged no problems.

Looking to add a HP Mediaserver EX495 (A NAS Device) that I have no problems with on another network. Upon booting it on the network it seems like it boots and tries to get an image from the PXE server and not boot itself.

No…you'll need to find out what's going on with the HP and fix it, as it definitely should not be starting out with a PXE boot. Possible there's some sort of firmware setting (re: boot order) that controls this similar to a regular PC?

I'm not sure if there is a way to define a boot order on the HP Mediasmart Server. There is a cable that you can purchase to hook up a VGA monitor to the server but was hoping for a cheaper fix.

Is there a way to limit the dhcp-boot command to a single port?? I would attach a switch to that port on the E3000 and if I need to RePXE image a computer I can just switch the network cable from one switch to other switch?? Would this be like a VLAN??
